TypedAggregateExpression

case class TypedAggregateExpression(aggregator: expressions.Aggregator[Any, Any, Any], aEncoder: Option[ExpressionEncoder[Any]], unresolvedBEncoder: ExpressionEncoder[Any], cEncoder: ExpressionEncoder[Any], children: Seq[Attribute], mutableAggBufferOffset: Int, inputAggBufferOffset: Int) extends ImperativeAggregate with Logging with Product with Serializable

This class is a rough sketch of how to hook Aggregator into the Aggregation system. It has the following limitations:
